Cases with reinforced corners belong to the shockproof class. Corner reinforcements act as a bumper/shock absorber — if the phone slips out of your hands and falls on its edge, the protected corners will minimize mechanical impact. The mobile device will remain safe and sound after the fall. Most often, corner protection is represented by special air chambers.
Cases with MIL-STD-810 protection allow you to safely use your mobile device in extreme conditions. Such models are distinguished by excellent shockproof properties, significantly increase the resistance of the phone to the negative effects of moisture, low and high temperatures, various kinds of vibration and other mechanical effects. Initially, the MIL-STD-810 standard was developed for the military, who use radio communications in the field.

Matte. The matte surface doesn't "gather" fingerprints and other dirt. Additionally, a case with a matte surface will not slip in your hands, providing the ability to securely grip your smartphone. The matte surface has a wide range of materials, from metal and plastic to leather and textiles.
—
Glossy. The glossy surface has a brighter and more noticeable design. Glossy covers are based on durable and reliable materials, it can be either metal with plastic or polyurethane. But at the same time, the glossy surface requires regular maintenance, which consists in wiping the cover from fingerprints etc. Additionally, a perfectly smooth glossy surface is prone to scuffs and scratches, so a glossy case requires careful handling.

Corrugated. This surface makes the case more comfortable and secure to use, as it provides a more secure grip and reduces the risk of your phone slipping out of your hands. In addition, this type of surface, like the matte rough surface, prevents marks and streaks from appearing on the surface. The vast majority of covers have anti-shock properties. The corrugated surface can be represented as a classic plexus of cross lines, as well as different elements of a textured array. Cases with a corrugated surface are most often created from plastic, polycarbonate and polyurethane.

Transparent.... Transparent case allows you not to hide the natural colour and texture of the smartphone. Protection with a transparent surface is most often made of silicone, less often — of polycarbonate or plastic. Usually, transparent cases provide good protection against scuffs and scratches.
— Mirror. The basis of the mirror surface can be either polished metal or tempered glass glued to a metal frame. In some models, a special grade of polycarbonate, fixed to a metal base, acts as a mirror. Mirror cases belong to the class of fashion cases and, above all, they are distinguished by high decorative value, making the smartphone visible from afar. Mirror protection also has disadvantages. So, a mirror unprotected with an oleophobic coating quickly gets dirty with fingerprints. Additionally, the glass surface can slide in the hands.
— Gradient. Gradient is a special way of coloring the cover, which involves uneven application of paint, that is, the dye is applied to different parts of the cover with different intensity. The gradient can be either monotone or colour. Covers with gradient painting have an increased level of decorative value.
— With a pattern. A special print (drawing) is applied to the back cover of the case. Covers with a pattern can be made from almost any material: metal, plastic, polyurethane, polycarbonate, wood, alcantara, etc.
